November 11. On this date in 1965, a message sent from the Universal House of Justice to all National Spiritual Assemblies announced the "Purification of the Most Holy Shrine of Bahá'u'lláh, the Qiblih of the Bahá'í World" by the removal of the remains of Díyá'u'lláh, who had been interred next to his father, Bahá'u'lláh, at the Mansion of Bahjí after his death in 1898. Díyá'u'lláh swayed between his two brothers, 'Abdu'l-Bahá and Ghusn-i-Akbar, in their argument.

November 11. On this date in 1965, a message sent from the Universal House of Justice to all National Spiritual Assemblies announced the "Purification of the Most Holy Shrine of Bahá'u'lláh, the Qiblih of the Bahá'í World" by the removal of the remains of Díyá'u'lláh, who had been interred next to his father, Bahá'u'lláh, at the Mansion of Bahjí after his death in 1898. Díyá'u'lláh swayed between his two brothers, 'Abdu'l-Bahá and Ghusn-i-Akbar, in their argument.

Díyá'u'lláh was born on August 15, 1864, in Edirne as the second son of Bahá'u'lláh through his second wife Fatimih (also known as Mahd-i-'Ulya).

Díyá'u'lláh married Thurayyá Samandarí, the daughter of Káẓim-i-Samandar (author of Tárikh-i-Samandar and one of the nineteen Apostles of Bahá'u'lláh to whom was addressed the Lawh-i Fu'ád) and sister of Ṭaráẓu’lláh Samandarí (who was appointed a Hand of the Cause of God by Shoghi Effendi in 1951).

Becuase they sided with Muhammad 'Alí in his argument with 'Abdu'l-Bahá, both Thurayyá and Díyá'u'lláh were declared Covenant-breakers. After his death in 1898, Díyá'u'lláh had initially been buried next to his father at the Shrine of Bahá'u'lláh at the Mansion of Bahjí. However, having been declared a Covenant-breaker, Díyá'u'lláh's remains were disinterred in 1965 in a process the Universal House of Justice described as a "purification... from past contamination."
